If the government doesn't have enough power, the wealthy won't need to bribe politicians to do their bidding. They will do their own bidding directly, and there will be nobody to stop them.
It's like, if you want to sell your cyanide penis pills under big government, you need to bribe someone. If you want to sell them under small government, you just... you just sell them, that's what.
There may be ways to design a government where power is better distributed, e.g. using sortition, but ultimately it needs to be richer and more powerful than its wealthiest citizens, otherwise these wealthy citizens will assess, correctly, that when push comes to shove, the laws won't apply to them, and they do not need the government's permission to do what they want.
Even a small government still has courts, in fact they would be a far more sizeable fraction of the government and thus a lot more effective. So if people like Epstein engage in criminal behavior, or even just unlawful behavior that they would be liable for, they can definitely be held accountable.
But suppose you have egalitarian nation N -- what stops the billionaire from non-egalitarian nation B from influencing your politicians? Especially if nation N is small and nation B is large.
Moreover -- why would low-level elites (think: entrepreneurs, small business owners, etc.) stay in nation N if it was more profitable to do business in nation B -- recall this is precisely the type of person that is often most mobile and internationalized.
